How do I fix UI-800-3 on Netflix? 7 fixes

I know seeing that unfamiliar code on your Netflix screen scared you. 

But I’m here to tell you that now, you can relax.

These 7 solutions will work for any platform like: 

So don’t worry. It’s not too late to enjoy your movie night yet.

And the first thing to do is to… 

#1: Power cycle your device

No matter what kind of device you have and how advanced it is… 

It’ll always have its limits. 

Too many tasks in too little time can make even technological devices give up. 

Just like humans would. 

But unlike us, your device doesn’t need a full good night of sleep to recover. 

Wanna know how much time it’ll take to make it work properly again?

Just 1 solid minute. 

Which is pretty amazing if you think about it.

And the way you can give your device this whole minute is through power cycling it. 

What’s that?” 

Power cycling is unplugging your device from the outlet and then plugging it back. 

It’s a simple process that can bring promising results.

But before you go and do it… 

Let me explain what happens during this process. 

When you power cycle your device, not only do you let it rest… 

You also clear the temporary data and information attached to its active apps. 

As mentioned earlier…

This Netflix error code usually signifies that your app is overloaded.

And so, you need to refresh it by power cycling. 

To power cycle any device:

Step 1: Unplug your device from the power source. 

You can unplug its adapter from the outlet or disconnect the power cable from the unit itself. 

If you have a device that doesn’t have a power cable like a Roku stick… 

Just unplug it from wherever it’s connected to.

Step 2: Press the power button (if there’s 1).

If you have a Smart TV, this is a recommended step.

While your device is turned off, press and hold its power button for at least 10 seconds. 

This will allow your unit to drain out all its power.

Step 3: Wait for 1 minute. 

If you pressed the power button of your device earlier, just wait for a whole minute. 

But if you didn’t, I suggest leaving it unplugged for up to 3 minutes.

Step 4: Plug your device to power again.

Step 5: Turn your device ON.

Step 6: Try streaming on Netflix once more.

#2: Sign out your Netflix account

On the 1st fix, you power cycled your device to restart its system.

Now, you’re going to do something similar to your Netflix account.

What you’re going to do is to sign out from your Netflix app. 

How’s that similar to power cycling?”

The process isn’t, but the results are. 

Signing out from your Netflix app will stop most of its tasks entirely.

This will allow your app to rest for a short duration like power cycling did to your unit. 

But I’m not watching through an app.”

If you’re using your browser, you should still do this fix. 

This process refreshes your account, no matter which platform you’re using. 

Now, the exact steps to sign out from Netflix will depend on your device. 

But for Smart TVs, this is how you can do it:

  1. Open the Netflix app.
  2. On its home screen, open the menu.
  3. Click Get Help or Settings.
  4. Select Sign out. 

I can’t access the Netflix home screen because of the error message.”

If that’s the case:

  1. Find More Details on your screen.
  2. Click it.
  3. Tap Sign out or Reset. 

Are you still lost on how to sign out from Netflix?

Then you should just use your browser to…

Sign your account out on all devices: 

  1. On a mobile device or PC, open your browser.
  2. Go to Netflix.
  3. On the top right corner, select Log in.
  4. Input your credentials. 
  5. On the right side of your screen, click Account.
  6. Find the SETTINGS section.
  7. From the list, select Sign out of all devices. 
  8. On the new page, click Sign out again.

Sign in to your Netflix account again and check if you’re still getting the error message.

#3: Clear your account’s cookies 

No, not the ones that you can eat.

Cookies in the world of technology refer to tiny pieces of data about you. 

They make it easier for your devices to customize your experience to how you’d like it. 

And although yes, these are helpful… 

They can also be the breeding ground for some bugs or glitches online. 

But no worries. 

You can clear these cookies just as fast as you can finish eating 1. 

To clear your account’s cookies:

  1. Find a mobile device or computer that you can use.
  2. Connect it to the same Wifi you use to stream Netflix. 
  3. Open your browser and head to
  4. On the upper-right corner, select Sign in.
  5. Input your credentials and log in. 
  6. Follow the instructions on your screen. 

Check if this fixed the error. 

If not… 

#4: Check your Internet connection

Netflix is a low-maintenance streaming platform. 


Because there aren’t too many requirements needed to watch it on your device. 

You can even play Netflix on a non-smart TV if you want to. 

But 1 thing that you can never neglect when using Netflix is…

Your internet speed. 

Being an online streaming app…

It requires a fast internet connection for a smooth Netflix experience.

But how fast is fast enough?

According to Netflix… 

You need at least 3 Mbps of internet speed to stream HD content on the app. 

But I don’t know how fast my internet is.”

Don’t worry. You can easily measure your internet speed in just a couple of minutes. 

This is how you do it: 

  1. Find a mobile device or computer.
  2. Connect it to your Wifi.
  3. Open your browser and go to
  4. Tap GO.
  5. Wait for the results to show up.

You should have at least 3 Mbps of internet speed to stream HD on Netflix. 

And if yours isn’t that high… 

Here are some tips to improve your Internet connection:

Tip 1: Power cycle your router.

Power cycling your router will allow it to refresh and load faster once it’s ON again. 

Just follow the same process you did when you power cycled your device earlier. 

Unplug your router, wait for 3 minutes, then plug it into its power source again. 

Tip 2: Use an ethernet cable. 

Wired connections relay faster and more reliable information than wireless connections do.

So if you’re using a TV or a Roku to stream your device, for example… 

Connect it to your router using a high-quality ethernet cable

Tip 3: Disconnect other devices from your network.

No matter how fast your internet is, it’ll slow down if it’s too congested. 

So, if possible, disconnect other devices from your Wifi while you’re watching Netflix. 

These 3 tips should be able to improve your internet connection. 

If you’re still experiencing network issues after trying them all… 

You should contact your internet service provider.

#5: Reinstall the app

Sometimes the app itself is the 1 causing this Netflix error.

So I suggest reinstalling it again to remove its glitches and bugs. 

Different devices need different steps to reinstall an app. 

But to give you an example of what the process looks like… 

I’ll teach you how to reinstall it on a Samsung TV. 

There are 2 steps to the reinstalling process, no matter what type of device you’re using:

  1. Deleting the app.
  2. Installing it again. 

But don’t worry. They’re both effortless to do. 

And like promised…

Here’s how you can reinstall Netflix on a Samsung TV:

Step 1: Delete the Netflix app.

  1. On your remote control, tap Home.
  2. Go to Apps.
  3. Find Settings.
  4. From the list, select Netflix.
  5. Tap Delete.

Note: For some TVs, the Netflix app is pre-installed, and you won’t be able to delete it. 

Step 2: Reinstall the app.

  1. Go to your Smart Hub,
  2. Tap the magnifying glass icon.
  3. In the search bar, type “Netflix.”
  4. Tap Netflix and click Install.

After installing the app again, try to stream on it once more. 

And talking about Samsung TVs… 

#6: Reset your Smarthub 

If you see this Netflix error code on your Samsung Smart TV

You should try resetting your Smart Hub. 

“What’s that?” 

Smart Hub is Samsung’s intelligent menu system.

And it’s the 1 responsible for storing your apps and the information connected to them.

Resetting this system resets all of your apps, including Netflix.

So it’ll most likely fix this UI-800-3 problem. 

To reset Samsung TV’s Smart Hub:

  1. Tap Home on your remote.
  2. On the left panel, go to Support.
  3. Click Self Diagnosis. 
  4. Scroll down and select Reset Smart Hub.
  5. Enter your TV’s PIN. The default is 0000. 

Note: This process will log you out of your apps and your Samsung account.
